Product description

Under its NBB® brand, Döhler offers innovative culture media for the fast and reliable detection of beverage spoiling microorganisms, such as Lactobacilli, Pectinatus and Megasphaera, in all samples that arise in breweries, as well as for the wine industry.

The desire for reliable and easy-to-use cultural detection methods has driven the development of the NBB® culture media, which has been ongoing for 30 years now. Clear and fast detection, a reliable result – even for a very low level of contamination in a large sample volume – and easy application for efficient laboratory work are the key driving forces behind these developments.

That is why renowned customers active in the beverage industry around the world place their trust in this high standard, extensive knowledge and expertise. Publications containing independent investigations and comparisons reinforce the product’s position as the market leader.

With their special growth promotion components and nutrients optimally tailored to beer and wine spoiling microorganisms, NBB® culture media offer a multitude of advantages.
